Holiday VI - Shark Pontoon.js

// You are given 5 variables;

// sharkDistance = distance from the shark to the pontoon. The shark will eat you if it reaches you before you escape to the pontoon.

// sharkSpeed = how fast it can move in metres/second.

// pontoonDistance = how far you need to swim to safety in metres.

// youSpeed = how fast you can swim in metres/second.

// dolphin = a boolean, if true, you can half the swimming speed of the shark as the dolphin will attack it.

// The pontoon, you, and the shark are all aligned in one dimension.

// If you make it, return "Alive!", if not, return "Shark Bait!".
